The flower in your post is very popular here and we do not know it as Nayan Tara flower. I also have this flower in front of my house and I bought this flower sapling from the fair last year and brought a small sapling and planted it in front of my house and within a few months it had grown a lot and was full of green leaves and after the flowers bloomed it looked much more beautiful.
Hola amiga @tammanna, gracias por su visita, amable atención y comentario, esta plantita es muy fácil de propagar, sus flores son hermosas, las llamo "mis vincas"...son muy adaptativas, esta nació en un lugar no deseado, pero decora mi entorno y allí la dejaré hasta que sea capaz de sobrevivir.
Saludos cordiales.
